your player sprite is the one with red and blue. try avoid the randomly flying bats with arrow keys to control your sprite. You can't move into green blocks. press space to fire a bomb. your aim is to bomb and fire to make the bats dead. if you make them dead 10 times, your score will be 10. therefore, you will win. if you touched the bats, it's game over. Also, if you fire a bomb, you must go away from it because if not you will die. Good luck! :)
